Parc de la Gradelle is unique. A geometric pattern, created with large custom-made concrete slabs and designed by Approches Paysage, allows unrestricted movement towards the entrances between the perennial and hydrangea beds.

Very large private gardens have been created on the roofs, using innovative watering techniques such as subirrigation. An open, natural-looking park simply surrounds the magnificent pagoda-shaped buildings designed by LRS Architectes.
